Description
ATS Thermal Bypass Valve Up-Grade for 2010-2012 6.7L Cummins
Protect your transmission from catastrophic heat failure with the ATS Thermal Bypass Block Upgrade (310-005-2356) . Designed specifically for 2010–2012 RAM 6.7L Cummins trucks equipped with the Max Tow Package (Sales Code AHQ) or Dual Transmission Oil Cooler (Sales Code NHT) , this billet aluminum block directly replaces the failure-prone factory unit, ensuring maximum fluid flow to your coolers at all times.
Whether you are running a 68RFE or Aisin AS68RC , the OEM bypass block (found in assembly 52014523AB ) relies on an internal thermostat that frequently sticks closed—routing superheated fluid straight back into your transmission. The ATS upgrade replaces the restrictive bypass valve with a solid, high-flow billet design, keeping fluid temperatures stable and your clutches protected during heavy hauls.
Product details
- Driver’s Side Wheel Well: Look near the fuel filter by the engine block. If you see a square aluminum block where the transmission lines join, your truck features the replaceable bypass block.
- In Front of the Radiator: A secondary "mini" radiator mounted in front of the main cooling stack confirms your truck utilizes the AHQ or NHT thermal bypass system.
- Direct OEM Replacement: Billet upgrade for the factory block in OEM Assembly 52014523AB (ATS Part # 310-005-2356).
- Prevents Overheating: Eliminates the failure-prone factory thermostat, removing the risk of stuck valves and rapid heat buildup.
- Maximum Cooling Efficiency: Unrestricted full-time fluid flow to the transmission cooler keeps operating temps significantly lower.
